|Played By:||Malcolm Scott|
A smuggler and former associate of Vala's, Caius disguised himself as a Monk and hid in a Monastery dedicated to a Goa'uld. However, his life on the Monastery had become tiresome as had bathing the poor, and wanted to escape. When Vala visited the Monastery to retrieve a power coil, Caius used it as an opportunity to get back his old ship which Vala previously had. He told Vala that the Coil was the only source of revenue for the Monastery, and she could only have it back, if she would return his old ship to him.
Vala and the rest of SG1 managed to get the ship back and returned it to Caius in return for the power coil, and Caius used the ship to finally escape the Monastery.
